If your home or workplace's central heating system isn’t warming up properly, there could be several reasons behind the issue. In this blog, we’ll go over some common causes and possible solutions:
1. Air in the System
Trapped air in the pipes or radiators is one of the main reasons a heating system fails to warm up. This air blocks the flow of hot water. Bleeding the radiators usually solves the problem.
2. Low System Pressure
If the pressure is too low, hot water won’t circulate efficiently. The ideal pressure is typically between 1 and 2 bar. You can check this using the pressure gauge on your boiler or heating unit.
3. Faulty or Incorrectly Set Thermostat
If the thermostat is set too low or is malfunctioning, it won’t signal the system to turn on. Make sure it’s set higher than the current room temperature.
4. Broken Circulation Pump
The pump is responsible for moving hot water through the system. If it’s stuck or not working, the heat won’t reach your radiators.
5. Boiler or Heater Not Starting
A problem with the boiler’s ignition, sensors, or power supply can prevent it from working. You may need to check error codes or contact a technician.
6. Limescale or Sludge Build-up
Over time, sediment or limescale can block pipes or radiators, reducing efficiency. Professional flushing or descaling may be required.
If none of these solutions work, it’s best to contact a qualified heating technician to inspect the system thoroughly. Regular maintenance can help prevent these issues and keep your heating system running efficiently.
